Only IPC selftest is missing the .gitignore file, so add it.
Also step_after_suspend_test is missing in breakpoints selftest
.gitignore file

Commit e56d82a116 ("arm64: cpu hotplug: ensure we mask out
CPU_TASKS_FROZEN in notifiers") fixed a long-standing ARM64 bug that
broke single-stepping after a suspend/resume cycle. Add a kernel
selftest to make sure this doesn't regress or affect other platforms.

This adds a Make include file which most selftests can then include to
get the run_tests logic.
On its own this has the advantage of some reduction in repetition, and
also means the pass/fail message is defined in fewer places.
However the key advantage is it will allow us to implement install very
simply in a subsequent patch.
The default implementation just executes each program in $(TEST_PROGS).
We use a variable to hold the default implementation of $(RUN_TESTS)
because that gives us a clean way to override it if necessary, ie. using
override. The mount, memory-hotplug and mqueue tests use that to provide
a different implementation.
Tests are not run via /bin/bash, so if they are scripts they must be
executable, we add a+x to several.

In case breakpoint test exit non zero value it will cause make error.
Better way is just print the test failure status.

Remove the run_tests script and launch the selftests by calling "make
run_tests" from the selftests top directory instead. This delegates to
the Makefile in each selftest directory, where it is decided how to launch
the local test.
This removes the need to add each selftest directory to the now removed
"run_tests" top script.

Bring a first selftest in the relevant directory. This tests several
combinations of breakpoints and watchpoints in x86, as well as icebp traps
and int3 traps. Given the amount of breakpoint regressions we raised
after we merged the generic breakpoint infrastructure, such selftest
became necessary and can still serve today as a basis for new patches that
touch the do_debug() path.
